The Ruwi Seizure: Chain of Custody and Sampling
During a routine inspection of a mobile-phone accessories shop in Ruwi, an authorised officer finds 320 power banks and chargers bearing the trademark of a major brand. The shopkeeper says they are 'copies' and offers to sell the officer 50 units at a discount. The officer seizes the items, puts them in the boot of his private car, and takes photographs on his personal phone. He gives one power bank to the complainant as a 'sample'. Ten days later he submits a one-page report to the Public Prosecution with no seizure list, no serial numbers and no signatures. At the prosecution, the suspect's lawyer argues that the evidence is contaminated and should be excluded.
1. Identify the evidence-handling and documentation failures in this seizure.

Failures. First, there is no seizure inventory prepared at the scene describing each item, quantity, model, serial number, condition and location. Second, the items were transported in the officer's private car rather than a secure official vehicle, breaking the documented chain of custody. Third, photographs were taken on a personal phone without preserving metadata or transferring them through an official evidence system. Fourth, a sample was handed to the complainant without a receipt, seal or sampling record, so control was lost. Fifth, the report was submitted ten days late and contained no signatures of the officer, the shopkeeper or an independent witness. Sixth, there is no record of secure storage or evidence-room entry. These gaps do not automatically make the evidence inadmissible, but they weaken its reliability and give the defence a strong argument. The officer's conduct may also amount to a disciplinary offence.
2. How should the seizure and sampling have been conducted?
Read the worked answer
Correct procedure. At the scene, the officer should identify each item, count it, record serial numbers and condition, and photograph it with a scale and an identifying card. A seizure report should be prepared in duplicate, signed by the officer, the shopkeeper and an independent witness, with a copy given to the shopkeeper. Items should be packed separately, sealed with tamper-evident seals bearing unique numbers, and transported in a secure official vehicle to a designated evidence store. The evidence-room log should record the date, time, seal numbers and receiving officer. If a sample is needed, a formal sampling procedure should be followed: photograph the sample in situ, seal it, issue a receipt, and retain the original under control or use an official sample. Digital photographs should be transferred to the official system with hash values or metadata preserved. Any admission by the shopkeeper should be recorded separately and voluntarily.
3. What can the officer do now to rehabilitate the file, and what are the limits?
Read the worked answer
Rehabilitation. The officer must not fabricate or backdate documents. He should prepare a supplemental statement explaining exactly what happened, including the private-car transport, the personal-phone photographs and the sample given to the complainant. He should attempt to recover the sample and document its condition, and locate the remaining 270 units, if possible, with a new inventory. He should transfer the photographs to the official system and preserve the original phone files. The prosecution should be informed of the chain-of-custody break so it can decide how to proceed. The limits are that the officer cannot recreate a contemporaneous seizure list, cannot manufacture signatures and cannot restore an unbroken chain after the fact. The case may still be supported by other evidence, such as the shopkeeper's admission, expert examination of the remaining items and complainant testimony, but the officer must be candid about the defects.
